What is the difference between dependent and controlled variables?
The controlled variable is the one that you chose to change while the dependant is the variable that changes because it is effected by the controlled variable
What is the difference between correlation and experiment?
An experiment is when the researcher manipulates the independent variable and records its effect on the dependent variable whilst maintaining strict control over any extraneous variables. A correlation is a statistical relationship between two or more variables. The researcher makes a change in one of the variables to see what is affected.
What is the difference between independent and dependent variable?
In any (well designed) experiment, there is one variable that the experimenter can control that affects one (or more) variables. The variable that the experimenter changes is called the independent variable. On the other hand, the other variable is dependent on the other for its change. Therefore, it is the "dependent variable."
What is difference between an instance variable and a class variable?
An instance variable is typically associated with an object instance of the class whereas class variable is not associated with any object instance. Static variables are referred to as class variables while non-static regular variables are called instance variables. Simply put, you will have as many instances of the instance variable as there are object instances. i.e., if there are 10 instances of an object, you will have 10 instances of that instance variable as well. But, there will be only one instance of the static or class variable. Instance variables are accessed as follows: objname.variableName; Class variables are accessed as follows: ClassName.variableName;
What is constant of variation in math terms?
It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.
What is the difference between controlling variables and using controls?
Controlling variables is when you make sure that only one variable is being tested at a time and that there are not other variables that will make your results unclear. Using a control is when you do a trial without the variable to see what the normal results are.
What does it mean when two variables have a positive correlation?
A positive correlation between two variables means that there is a direct correlation between the variables. As one variable increases, the other variable will also increase.
What is one difference between a variable and a numerical expression?
The variable.
What is a Cartesian graph used for?
To illustrate the relationship between one or more dependent variables and a variable (often an independent variable).
What is the difference between correlation analysis and regression analysis?
In linear correlation analysis, we identify the strength and direction of a linear relation between two random variables. Correlation does not imply causation. Regression analysis takes the analysis one step further, to fit an equation to the data. One or more variables are considered independent variables (x1, x2, ... xn). responsible for the dependent or "response" variable or y variable.
What is ordinary variable?
Ordinary variable are those variables that can store only one (1) variables
What is Variable Shadowing in Java?
In Java, there are three kinds of variables: local variables, instance variables, and class variables. Variables have their scopes. Different kinds of variables have different scopes. A variable is shadowed if there is another variable with the same name that is closer in scope. In other words, referring to the variable by name will use the one closest in scope, the one in the outer scope is shadowed.A Local Variable Shadows An Instance VariableInside a class method, when a local variable have the same name as one of the instance variable, the local variable shadows the instance variable inside the method block.
Definition for decision models and decision variables?
Decision variables are the variables within a model that one can control. They are not random variables. For example, a decision variable might be: whether to vaccinate a population (TRUE or FALSE); the amount of budget to spend (a continuous variable between some minimum and maximum); or how many cars to have in a car pool (a discrete variable between some minimum and maximum).
What is control variable?
what is an controlled variable. we need to know it for our science proformance asscement!!! From a friend in need!
What is a relationship between two variables in which one variable increases as the other decreases?
This is called an "inverse" relationship.
What does a correlation of -0.9 mean'?
as one variable increases the other variable decreases
When can we say that a function is a relation?
When it doesn't fulfill the requirements of a function. A function must have EXACTLY ONE value of one of the variables (the "dependent variable") for every value of the other variable or variables (the "independent variable").
